Ice-free roads-using renewable energy
• Project Goals• Reduce environmental negative impacts• Reduce risk of traffic accident • Reduce road maintenance operation and activities
PhD student: Raheb Mirzanamadi, Josef JohnssonSupervisor: Bijan A. Zarrabi
ObjectiveTo evaluate the environmental and economic impacts of activitiesrelated to the construction and rehabilitation of new and existingNorwegian open roads by means of:
– Environmental life cycle assessment (LCA) and– Economic life cycle cost analysis (LCCA).

Public transport All combined
Non-motorized Private transport
• To achieve the full potential of investments in traffic systems we need to understand the complete urban mobility system, including the non-motorized.
• New theory and methodology inarchitecture called space syntaxopens new possibilities.
• Collaboration with similar projects atTU Delft of Randstad (Gil & Read
2013)

Competitive steel & composite bridges - fatigue life enhancement through post-weld treatment
PhD student: Poja Shams HakimiProfessor Mohammad Al-EmraniStructural Engineering Steel and timber structures
Aim– Make steel bridges more competative by
• Eliminating susceptibility to fatigue damage• Make possible the use of higher strength steels
– Step toward sustainability in bridge construction by• Efficient use of material Lighter structures Less
transportations and cheaper sub-structures
– A preliminary study is carried out• 20 – 30% material saving for simply supported steel
railway bridges• Steel can be used S460
– Higher grade not beneficial

Biodiversity-promoting stormwater systems
Aim and ObjectivesDevelop solutions to promote aquatic biodiversity in stormwater systems• Identify factors that influence
aquatic biodiversity• Develop a model to simulate
the influence of different factors
• Implement the model to design biodiversity-promoting stormwater systems
• Provide design recommendations for stormwater systemsPhD student: Zhenhua Sun
Supervisors: Ekaterina Sokolova, Sebastien Rauch and Sondre Meland
Progress of the projectIdentification of key factors affecting biodiversity and modeling tools through a literature review.• effects of roads on aquatic biodiversity, • sustainable urban drainage systems, • measures of aquatic biodiversity, • factors affecting biodiversity, and • modeling tools to simulate the influence of roads on aquatic
biodiversity.Next step – data analysis using modeling. The models that will be used could be statistical, hydrological or biological models.

Biologically induced degradation of sprayed concrete in subsea tunnels
PhD student: Sabina Karacic
PROBLEM: - A novel deterioration process has recently been discovered in several Norwegian subsea tunnels resulting in rapid degradation of the sprayed concrete matrix and destructive corrosion of the steel fibers in areas with leakages of saline groundwater. - Thick microbial biofilms, with iron and manganese oxidizing bacteria are involved in the degradation process.
The tunnel at the test site, one of the tunnel locations with extensive biofilm formation and close up of the biofilm on the sprayed concrete.
Supervisors: Prof. Britt-Marie Wilén; Assistant Prof. Frank Persson (WET), ChalmersSenior Engineer Per Hagelia at NPRA
The aim of this project is to increasethe understanding of the mechanismsinvolved in the biologically mediatedcorrosion of sprayed reinforcedconcrete in subsea tunnels.
Now (Phase I):1. Sampling (Test site,
Oslofjord tunnel) 25/10/2015; 01/09/2015 50 samples
2. Investigation of the composition of microorganisms on the concrete:- DNA/RNA extraction and amplification-sequencing of specific regions of the 16S rRNA gene (MiSeqIllumina platform )
What shall we do now?
